SIRIUS auxiliary contactor, size S00 — 3 NO, 10 A
The 6 kV surge voltage resistance and pollution degree 3 rating mean it holds up in industrial panels where transient spikes and conductive dust are routine — not a clean-room part. The IP20 front protects against finger contact but expects enclosure protection for washdown or outdoor use.
Contact reliability and mechanical life
The contact reliability spec — one incorrect switching operation per 100 million at 17 V, 1 mA — matters when this contactor feeds a PLC input sensing a dry contact. At those low-energy levels, oxide films on standard contacts can cause intermittent opens; this part is designed to switch reliably at signal-level loads, not just power circuits. Mechanical life is 30 million operating cycles typical, which for a frequently cycled auxiliary relay in a packaging line or conveyor system translates to years of service before replacement.
Shock resistance is 10g at 5 ms and 5g at 10 ms, adequate for panel-mounted equipment in most industrial machinery.
Compliance documentation
The substance prohibition date of 07/01/2006 aligns with the RoHS directive effective date, indicating the part is RoHS-compliant. For REACH, UL, and IEC documentation, the SIRIUS series typically carries these certifications; the specific approvals for this order code should be confirmed from the manufacturer's declaration or the product datasheet available on request.
